The birth of a book 8: digital printing

The biggest difference between digital printing and traditional printing is that it omits the processes of producing film and printing PS plates, and directly realizes the printing process from computer to paper. The imaging principle is also different from offset printing. It is suitable for small batches and personalized prints. It can be as few as 100 parts. If you want to have several books of your own, such as commemorative books, travel notes, photo albums, etc., digital printing is the most economical and ideal.

The working principle of the digital printing machine is that the charger charges a layer of charge on the surface of the recording drum, and the dot matrix information of the content (such as characters) to be printed by the printer controller is irradiated to the surface of the charged recording drum in the form of a laser beam to release Remove the charge at all positions that are not required by the printing point. When the recording drum rotates to the toner cartridge, the charge at the position required by the printing point will attract the toner. When the recording drum with the toner shape rotates to At the printing device, the printing paper is between the recording drum and the transfer device. The stronger reverse charge added to the transfer device will attract the zigzag toner on the recording drum to the printing paper. The heated part The toner on the paper will be melted and dried, and the glyphs already on the printing paper will be firmly stored to complete the printing process.

There are three print sizes for digital printing: A4 (297mm × 210mm), A3 (420mm × 297mm) and SRA3 (450mm × 320mm). Digital printing is suitable for printing on paper with a thickness between 80g and 250g.

Digital printing has a variety of applicable documents. In addition to professional production software, office software and even printed drafts can be used. Of course, the most standardized is to provide electronic files in PDF format, which will make the printing process fast and accurate. Digital printing can do it: it's advisable to wait, and the copies are different.
